GMB(X)24-3
On/Off, Floating Point, Non-Spring Return, 24 V
Torque min. 360 in-lb for control of damper surfaces up to 90 sq ft.
Application
For on/off and floating point control of dampers in HVAC systems. Actuator sizing
should be done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means
of its universal clamp. A crank arm and several mounting brackets are available for
applications where the actuator cannot be direct coupled to the damper shaft.
Operation
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement.
The GMB(X) series provides 95° of rotation and a visual indicator indicates position of
the actuator. When reaching the damper or actuator end position, the actuator
automatically stops. The gears can be manually disengaged with a button on the
actuator cover.

Proportional control damper actuators shall be electronic direct-coupled type, which
require no crank arm and linkage and be capable of direct mounting to a shaft up to
1.05” diameter. Actuators must provide proportional damper control in response to a 2
to 10 VDC or, with the addition of a 500 Ω resistor, a 4 to 20 mA control input from an
electronic controller or positioner. Actuators shall have Brushless DC motor technology
and be protected from overload at all angles of rotation. Actuators shall have reversing
switch and manual override on the cover. Run time shall be constant and independent
of torque. A 2 to 10 VDC feedback signal shall be provided for position indication.
Actuators shall be cULus listed, have a 5-year warranty, and be manufactured under

is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC
monitors and controls the actuator’s rotation and provides a digital rotation

Actuators with plenum rated cable do not have numbers on wires; use
color codes instead. Actuators with appliance cables are numbered.
21
Provide overload protection and disconnect as required.
222
Actuators and controller must have separate transformers.
233
Consult controller instruction data for more detailed information.
244
Resistor value depends on the type of controller and the number of
actuators. No resistor is used for one actuator. Honeywell® resistor kits
may also be used.

Application
For proportional modulation of dampers in HVAC systems. Actuator sizing should be
done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means
of its universal clamp. A crank arm and several mounting brackets are available for
applications where the actuator cannot be direct coupled (only the positive part of the
sine wave) to the damper shaft.
The actuator operates in response to 0 to 20V phasecut control input only on the
positive part of the sine wave from an electronic controller or positioner. A 2 to 10
VDC feedback signal is provided for position indication.
Operation
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement.

The GMX24-PC actuators use a brushless DC motor, which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent
damage to the actuator in a stall condition. Power consumption is reduced in holding
mode.
Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto
the actuator body for signaling and switching functions.

Functional Profile according to LonMARK
K®
The LON-capable damper actuator is certified by LonMARK®. The actuator functions
are supplied with the LonWorks® network as standardized network variables
according to LonMARK®. The Node Object #0, the Damper Actuator Object #8110
and the Open Loop SensorObject #1 are implemented in the actuator.
Node object #0
The node object contains the object status and object request functions.
nviRequest
SNVT_obj_request
Input variable for requesting the status of a particular object in the node.
nvoStatus
SNVT_obj_status
Output variable that outputs the current status of a particular object in the node.
nvoFileDirectory
SNVT_address
Output variable that shows information in the address range of the Neuron chip.
Damper actuator object #8110
The actuator object is used to map the functions of the MP actuators to the
LONWORKS® network.
nviRelStpt
SNVT_lev_percent
The nominal position is assigned to the actuator via this input variable. This variable is
normally linked to the output variable of an HVAC controller.
nviActuateState
SNVT_switch
A preset position is assigned to the actuator via this input variable. Note on priority:
The last variable that was active, either nviActuatorState or nviRelStpt, has priority.
nviManOvrd
SNVT_hvac_overid
These input variables can be used to manually override the actuator into a particular
position.
nvoActualValue
SNVT_lev_percent
This output variable shows the current actual position of the actuator and can be used
for control circuit feedback or for displaying positions.
nvoAbsAngle
SNVT_angle_deg
This output variable shows the current angle of rotation of the actuator
or the valve and can be used to display the position or for service purposes.
Open loop sensor object #1
A sensor can be connected to the rotary actuator. A passive resistance sensor (e.g.
Ni1000), an active sensor (output 0 ... 32 V) or a switch (on/off) can be connected. The
open loop sensor object transfers the measured sensor values to the LONWORKS®
network.
nvoSensorValue
SNVT_xxx
This output variable shows the current sensor value. Depending on the connected
sensor, the output variable can be configured via the sensor plug-in and specifically
adapted to the system.
The SNVT_... can be configured as:
SNVT_temp_p
SNVT_lev_percent
SNVT_lux
SNVT_temp
SNVT_abs_humid
SNVT_press_p
SNVT_switch
SNVT_enthalpy
SNVT_smo_obscur
